BUMPER.

Application nl ed .Tune 30, 1924. Serial No. 723,075.

To all whom t may conce/m.'

Be it known that I, ALBERT J.' ROTH, a citizen of the United States, and a resident of the city of Chicago, county of Cook and State of Illinois, have inventedcertain new and useful Improvements in a Bumper, of which the following is a specific( tion.

My invention relates to a bumper, and more particularly to the means for resillently mounting the bumper on an automobile or vehicle, and has for its object the provision of a bumper with strong and durable means for mounting the same on a vehicle so that it will yieldably take up and cushion the shock or impact caused by an encountered vehicle or object.

Y Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of parts hereinafter described and claimed. v

The invention will be best understood by reference to the accompanying drawings forming a part of thisspeciiication and in which, l

Fig. 1 is a plan view of 'my'inventlon mounted `in position on an automobile; Y

Fig. 2 is a front view of myvimproved bumper;

Fig. 8 is an enlarged vertical sectional view taken on line 8 8 of Fig. 2;

Fig. 4 is an enlarged horizontal sectional view taken ou line 4 4 of Fig. l8;

Fig. 5 is a vertical sectional view of the spring mechanism and casing, taken on line 5 5 of Fig. 4; and

Figs. 6 and 7 are horizontal detail scctional views taken on lines 6 6 vand 7 7 of Fig. 5, respectively.

The preferred for m` of construction illustrated in the drawings comprises an impact member or bumper bar preferably consisting of a pair of parallel bars 10 and 10 spaced one over the other, and preferably in the form of T-bars, and further comprises means for yieldably mounting theimpact member at the front or at the rear of a vehicle, like an automobile, for effectively cushioning the impact of an encountered object or vehicle.

My improved means forA yieldably mounting the impact member comprises a casing positioned adjacent each cnd of said inember and `preferably including two cylindrical parts 11 and '11 placed vertically in axial alinement, one over the other, each casing having a bracket plate l2 fastened on the outward side and a substantially triangular plate 18 on the inward side byy pairs of bolts14 and 14. are fastened to the framebars 15 of an automobile 16 by lmeans of bolts 17 or the like, and furthermoreby means of links 18 and bolts 19 and 20, the boltsA` 19 and plurality of openings 21 and 22 (see Fig. 8) in bracket plates 12 and links 18 enabling the two casings to be adjusted vertically. The

These plates 12 and 18 parts 11 and 11 lof each casing are proy vided with caps 28 and 28, at the top and bottom respectively, which yare adjustably mounted thereon'by means 4ofserra'tions or teeth 24 or 24 and are held in Xed position by a bolt 25 and ay suitable `.fastening nut. A disk or plate 26 is rotatably mounted between the casing parts 11 yand 11', and springs 27 and 27 `are ymounted in said parts 11 andll and areseated orbear with*v the inner ends transversely or substantially radially of the vcasing against lugs or means 2S or 28011 said plate, and with the outer ends against lugs vormeans 29 and 29 on caps 28 and 28. An integral arm 26 eX- tends from plate 26 forward and outward from the casing and ispiVOted by a bolt 8() to forks 81 of a link 82, and a shoulder 88 on said link limits inward movement of this pivotal connection. Each link ,82' is piv otally connected at its outwardQend with forks'i84 and bolts 85 to impact members orbumper bars 10 and 10', a plurality of openings 86 for receiving said bolts being provided in said. barsto rmake the bumpersuitL able for automobiles or vehicles of diiferent widths. V ',v i y My improved bumperis' mounted on the' frame members of the automobile or vehicle, as indicated in Fig. l1, and when an impact or shock comes upon the bars 10 and 10, the links 82 will move thearms 8l with the pivotal connections 80 outwardly, thereby flexing the springs 27, whichvwill gradually and yieldably cushion the shock or impact;

the caps 28 providing adjustability for the c tension of the springs 27 and these springs are placed slightly under tension when the departing from the spirit of the invention.`

I, therefore, do not Wish to be limited to the precise detailsot construction set forth, but desire to a'vail myself ot such Variations and modilications 'as come Within the scope of theappended claims. y

Having described my invention, `What I lclaim 'as ne'W and desire to secure by Letters Patent is: c

l, A bumper comprising an impact member and means for yieldably connecting itio a trame member of va AVehicle, said means comprising 'a casing withv an adjust'able'cap, means ior mounting 'said casing on one of said members, a coil spring in said casing and 'with "one end engaging means on said cap, a liat transyersely yeit'ending member rotatably mounted Within said casing and having a part engaging the 'other end of said spring, and link means tor pivotally connecting said rotatable means With the other otsaid'mie'mbers.

2. A bumper comprising an impact member, m'eansioryieldably monntin'g it on a frame member 'of 4a yfe'hicl'e, said me'ans comprising a pair 'o'f'alined 'cylindrical casing parts', a bracket attached to both of vsaid cylindrical parts, and having means for holding the case in' position on one or 'said members, an element rotatably mounted between said cylindrical parts, a coil spring in each cylindrical part and with one end engaging a part or said rotatableelement, a cap mounted on 'ea-ch cylindrical part 'and having means'to engage the Vother end of said spring, 'and means for 'connecting said 'rotatable element to the Iother Vof said members.

3. A bumper comprising an impact memb'er vand `means tor yieldably mounting it on a member ot "a Vehicle,` `said means comprising a casiiig-with -means thereon for securing it t'o one of said members, 'plate means rotatably mounted in said casing, a coil 'spring pressing With one end trans versely of said casing against means Yon said plate, a cap With rmeans pressing 'against the #other end 'ot said spring transversely of said casing, 'and means for pivotally con# nect'in'g said plate with the other of said members.
